VENDING-MACHINE.

Specification of Letters Patent.

Patented Jan. 13,1914.

Application filed January 4, 1913. Serial No. 740,199.

To all whom it may concern Be it known that we, HENRIETTA T. VVER DEN and SARA L. WV. Con, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Vending-Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in vending machines and more particularly shutter-operating means for the coin slot the object of the invention being to provide simple and efficient means for automatically controlling the closing of the coin slot of a machine for vending stamps or tickets when a roll of such stamps or tickets shall have become exhausted.

With this object in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is an elevation of a vending machine (with the casing omitted) showing an embodiment of the invention; Fig. 2 is a plan view and Fig. 3 is a partial sectional view.

1 represents the coin chute of the machine, provided at its upper end with a hollow top plate 2 having alined slots 3 constituting the coin inlet.

Stamp or ticket feeding or discharging devices are indicated at 4, 4, and the operation of these is controlled by devices which are actuated and controlled by a coin. The construction of these devices do not however, constitute features of the invention hereinafter specified in the claims and need not be herein specifically described.

The stamps or tickets are to be fed from supply rolls 6-7 and the proper feeding of the strips to the drums of the feeding or dis charging devices ll, by means of rollers 7 These rollers are mounted on an l.- shaped arm 8 pivotally mounted on the same shaft 9 which carries the reels of stamps or tickets. A hand lever 10 is secured to the L-shaped arm 8 to enable an attendant to raise the rollers 7 when it is desired to thread the strips over the fed drums, and this lever normally engages a stop 11 on the fixed framework 12 to limit the descent of the rollers.

The supply rolls of stamps or tickets are mounted on reels 13 and the hub 14 of one of these reels is provided with an annular groove 15. A horizontal shaft 16 is mounted in suitable bearings 17 on the frame 12 and one end of this shaft is provided with an arm 18 (preferably made curved or hookshaped at its free end, as at 19) which bearmg against the roll 6 of stamps or tickets and which, when the stamp or ticket roll has become exhausted from the hub 14, is adapted to enter the annular groove 15 in said hub, for a purpose which will be hereinafter explained.

A shutter 20 is disposed within the hollow top plate 2 of the coin chute 1 and is movable therein in such manner that it may be operated to close the coin inlet slots 3 when the stamps or tickets shall have become exhausted from the reels. The shutter 20 may have indicated thereon, the word Empty as shown in Fig. 2.

The shutter 20 is provided with an arm 21 which projects beyond one end of the top plate 2 and is pivotally attached, at 22, to the frame 12. The shutter arm 21 is provided with a cam slot 23, through which the vertical arm 24 of a bell-crank 25, passes freely. The bell-crank 25 is pivotally mounted on the frame 12 and to its horizontal arm 26, one end of a rod 27 is pivotally attached-the other end of said rod being pivoted to a crank arm 28 on the shaft 16. A spring 29 is attached at one end to the frame 12 and at the other end to the arm 26 of the bell-crank 25.

When the reels are supplied with rolls or stamps or tickets, the arm 18 will be pressed against one of said stamp or ticket rolls, by the action of the spring 29 and the vertical arm 24 of the bell-crank 25 will be disposed at or near one end of the cam slot 23 in the shutter arm 21, thus holding the shutter out of line with the coin inlet slots 3. The cam slot 23 is so formed that the arm 24 may move freely through a portion thereof without moving said arm or the shutter, and the parts are so proportioned that the arm 21 may move a distance equal to approximately one-half the diameter (less one half the diameter of the hub 14) of a stamp or ticket roll, while the arm 24 of the bell crank is moving freely through a portion of the cam slot 23. When the stamp or ticket roll shall have become exhausted from the hub 1 the hook-shaped free end of the arm 21 will be permitted to enter the annular groove 15 in said hub. The arm 21 will be caused to thus enter the groove 15 by the operation of the spring 29, and the bell-crank 25 will be moved sufficiently to cause its vertical arm 24 thereof to so cooperate with the wall of the cam slot 23 in arm 21, as to move said arm on its pivotal support and cause the shutter to close the coin inlet slots 3, thus indicating that the supply of stamps or tickets have been exhausted from the reels.

Having fully described our invention what we claim as new and desire to secure by Letters-Patent, is:

1. The combination with the casing of a vending machine having a coin slot in its top, and a supply reel, of a horizontally disposed pivoted shutter for the coin slot, having a cam portion, an arm to bear on a stamp or ticket roll on said reel, and connections between said arm and the cam portion of the horizontal shutter for turning the latter to close the coin slot when the stamp or ticket roll becomes exhausted.

:2. The'combination in a vending machine having a coin slot in its top, of a horizontally disposed pivoted shutter for closing said slot and having a cam portion, a hub for a stamp or ticket strip, a shaft, an arm carried by said shaft and adapted to bear on a stamp or ticket roll on said hub, a crank on said shaft, and connections between said crank and the cam portion of the shutter for actuating the latter.

3. The combination in a vending machine having a coin slot, of a shutter for said slot, said shutter having a cam portion, a grooved hub, a rocking arm, means for pressing said arm toward the grooved hub, and connections between said arm and the cam portion of the shutter for operating the latter.

and having a cam slot, a bell-crank having one arm projecting through said cam slot, a rod connected with the other arm of the bellcrank, a shaft, a crank on said shaft connected with said rod, a grooved hub, an arm on said shaft movable relatively to said hub, and a spring fixed at one end and connected at the other end with one arm of the bellcrank.

In testimony whereof, we have signed this specification in the presence of two subscribing witnesses.
